Ya, I'm gonna have to go with Cubase/Nuendo for my answer as far as "In The Box" tools. In fact when I was hunting around for a modern DAW (I was on a hand me down Nuendo2 system before I showed up here) it came down to Cubase and SONAR. SONAR had the (far) more robust FX/Instrument suite which is what I needed after having to completely abandon my jam spaces/live bands/drum kit/amps/misc. outboard gear/etc.
And that was during the X1 phase. The package got a LOT better since then (particularly the inclusion of AD2 because SD3 just wasn't cutting it for my needs). I simply could not afford to have to buy a whole pile of "extras" on top of building my new system AND the DAW itself otherwise I likely would have stuck with Steinberg.
Now though I am addicted to the Prochannel way of doing things and aside from amp sims I mostly use the PC stuff for my mixing. The whole reason I like SONAR so much is because I feel like I'm working with actually outboard gear/board(s). I find most of the other programs are too abstract in their GUIs and sound shaping and since the PC modules are mostly based on gear that can be easily researched and has been in use for decades in studio production. I think they modeled the most useful stuff for a clowno rock dino like meself (even if I did not know it at the time of purchase).
Losing the PC modules would be a catastrophe to me so I'm just going to squat on SONAR as is and not necessarily "lock down" my system but make sure I can keep working as I have been. I've also been working with Reaper quite a bit but a) no PC modules (pretty much every other Cake plug works though), b) Reaper is ultra abstract with it's GUI IMO and I don't like tracking/mixing/comping in it and c) it's an extremely complex program that requires a LOT of study to make it do what I need (even more so than SONAR was and it took me YEARS to get my blapples in the game there).
Everyone here talks about S1 like it's the obvious alternative to SONAR and maybe it is similar in its workflow but if I'm gonna drop even more money that I don't have on a new DAW I gotta say Cubase is probably the most logical choice for me. Especially considering that's what most of the indie Canuck studios use (aka my weirdo friends and what I hear from the music shop guys most of the young artists are using). They also seem to have something similar to the PC as far as onboard channel FX for easy tweaks... just not the same models/GUI.
I don't see me changing a bloody thing for a loooong time though. After X3 came out I was able to work the way I intended to when I first bought in (X1 was useable but problematic at times, X2 was a nightmare).
I just want to make music and have been able to do that. As long as I can continue to do so then I got no problems. Shiz... I could go the rest of my life using pretty much what I have now if nothing blows up on me.
